Title: Improved diamond deposition cell
Inventor: CANN GORDON L
IPC: C23C16/27
Filed: 1990-01-08
Abstract: In a first embodiment of an improved diamond deposition cell, a chamber is evacuated to a low pressure and a graphite element in the chamber is heated to a selected high temperature and heats a substrate positioned within the chamber spaced by a selected gap from the graphite body to a selected lower temperature. Hydrogen or a mixture of hydrogen and hydrocarbon gas is admitted to the chamber and part of the hydrogen reacts with the hot graphite body to form atomic hydrogen and hydrocarbon gases. Hydrogen and hydrocarbon gases cycle repeatedly across the gap between the facing surfaces of the body and the substrate in the kinetic regime resulting in a net transfer of carbon to the substrate and its deposition as diamond crystals or film on the substrate. In a second embodiment, the graphite body is heated by combusting gases in a cavity therein. Products of such combustion, hydrogen and, optionally, additional hydrocarbon gas are admitted to the gap between the surfaces of the graphite body and the substrate. The temperatures of the facing surfaces, the pressure in the gap and the ratio of the constituent gasses result in carbon atoms being deposited on the substrate in the form of diamond film and other carbon products.

Patent CA-2025657-A1 (CA)
Inventor: SWANSON SCOTT C
IPC: A61F13/15
Filed: 1990-09-18
Abstract: A bus access controller. An interface circuit (22) controls the access of a host computer (10) and a microprocessor (23) to one or more UARTs (14, 15). The microprocessor (23), which has no provision for waiting for a data transfer, is required to provide a signal of its intent to perform a data transfer prior to beginning the actual data transfer. The signal is identical to the actual data transfer operation. If the host (10) attempts a data transfer operation while the microprocessor (23) is conducting a data transfer operation, or if the host data transfer cannot be completed prior to the time that the microprocessor data transfer will commence, then the interface circuit (22) signals the host (10) that the data transfer will take additional time by deasserting the I/O  READY line (12a). Once the microprocessor data transfer is completed then the I/O READY signal is reasserted and the host data transfer is completed, Bus contention problems and data loss are therefore prevented and the host (10) waiting time is minimized.

IPC: H01F21/04
Filed: 1990-10-22
Abstract: Abstract of the Disclosure The inductance value of air-core coils are adjusted using automated methods and inexpensive, noncomplicated apparatus.  Adjusting tools are provided which displace coil turns in a linear motion with respect to the coil centerline.  Specifically, the coil turns can be displaced by sliding perpendicularly to the coil centerline or by rotating a group of coils in order to modify the coil inductance.  The adjusting tools used and the method of coil-turn displacement allow the automated method to reincrease the inductance of a coil in the event that displacement causes an over-decrease of inductance.

Title: Dimpled plate multi-staged flash evaporator
Inventor: ELMORE CARL L
IPC: B01D3/06
Filed: 1990-10-22
Abstract: ABSTRACT       A multi-stage flash evaporator is constructed so that the evaporator elements are dimpled plates mounted so that they extend horizontally.  One, two, or more sets of plates may be mounted in each evaporator stage, the sets stacked upon one another in a tier arrangement.  Each stage may be formed by a circular cross-section vessel, with I-beams -- or like supports -- extending horizontally at about the horizontal diameter of the vessel, and supporting the dimpled plates on them.  A condensate collection trough is mounted below the dimpled plates and at the I-beams, the I-beams having openings in them through which condensate collected by the trough passes from one end of the vessel to the other.  The hot liquid -- such as sea water to be desalinated -- to be evaporated is passed into a bottom chamber of each stage vessel, with vapor flowing upwardly through demistors and channels, into contact with the dimpled plates, and the condensate falling as a thin film down the plates and collecting in the condensate trough.  The brine is preheated by passing it into the passageways within the dimpled plates counter to the direction of flow of the brine into and through the bottom chambers.  The plates are preferably titanium or aluminum, but may be stainless steel if brackish water is distilled.  A sacrificial anode may be mounted adjacent the plates.

IPC: G05D23/13
Filed: 1990-11-07
Abstract: HYDRONIC HEATING WATER TEMPERATURE CONTROL SYSTEM   ABSTRACT OF THE INVENTION      A three-way modulated diverting valve is provided in the return line to the boiler of a hydronic heating system between the heating loop return and the boiler return, the valve having its input from the heating loop return, one output to the boiler return and the second output to the heating loop supply, so that the valve diverts some of the cooler return water to the boiler hot supply water, diluting the supply water to reduce the temperature of supply water that feeds the heating loop; and the valve is modulated by a feedback signal representative of the temperature of the diluted supply water. In a preferred embodiment, the feedback modulation is accomplished using a non-electric thermostatic actuator head that drives the valve stem and is controlled by a capillary temperature sensor, the sensor bulb being immersed in the diluted supply water or clamped to the supply line next to the heating loop supply so that it is at the temperature of the diluted supply water.  In operation, capillary fluid in the bulb expands with temperature applying a pressure force through the capillary to the actuator head which drives the valve stem, and so the diverting valve is modulated to increase or decrease the flow of return water to dilute the supply water as necessary to maintain the diluted supply water temperature at a predetermined value.

Abstract: Circuits are provided whereby rechargeable batteries and cells are charged very fast by a controlled current, and substantially at a rate never exceeding the ability of the battery or cell to accept current--i.e.: to convertelectrical current to stored chemical energy. The resistance free terminal voltage of the battery or cell is detected during an interval when the charging current is interrupted, and compared against an independent reference voltage to control the charging current when a difference between the reference voltage and the sensed resistance free terminal voltage exists. The reference voltage may be altered at any instant in time, as a function of the ambient temperature, or the internal temperature or pressure of the battery, as a function of the charging current when it is within a predetermined range, or if a particular change in the value of the charging current occurs over a predetermined period of time. Charging characteristics may also be controlled and altered either through the passage of time or as a consequence of predetermined conditions occurring. The various provisions preclude thermal runaway for example, and assure very rapid and complete charging operations no matter what may be the condition of the battery--provided it is capable of accepting charge--and for various kinds of rechargeable batteries and cells including nickel cadmium, lead acid, and so on.
